Study on Temperature and Humidity Distribution and Monitor Arrangement in Tobacco Aging Warehouse

In the process of tobacco storage and conservation, the temperature and humidity are monitored in the aging warehouse. Due to the large number of warehouses, the equipment investment and maintenance cost are high. So the arrangement of monitor is optimized, which can not only reduce the equipment investment, but also comprehensively and accurately monitor the temperature and humidity. The temperature and humidity monitors ware used to collect data through NB-IoT. After the experimental analysis, the results show that: (1) The hierarchical distribution in the vertical direction of temperature and humidity in the warehouse is significant. (2) The horizontal distribution of temperature and humidity is more significant in the lower layer, but less significant in the higher layer, especially in the upper layer. According to the vertical and horizontal distribution characteristics of temperature and humidity in tobacco aging warehouse, the representative monitoring points are selected at each layer. These monitoring points are evenly distributed in the low temperature and high humidity areas of the warehouse, and the location is simple and easy to use.
